Unable to Access Vivaldi Coordinates

[anjumm]

Hello, hope everyone is well. I am trying to use Serf and extract network coordinates for each node. However I am unable to find a way to extract them. Can you kindly give me an idea where can we access them? I am using 20 nodes and I have all serf agents connected. I am more interested in getting the coordinates. Appreciate help in advance.

The Serf rtt command is for querying the coordinates system.

$ serf rtt osboxes
Estimated osboxes <-> disboxes rtt: 6.231 ms

Thank you for guidance. However can we also get the coordinates in 2 dimensions or even more just like how vivaldi works? RTT will give an estimate of latency but I am interested in nodes having virtual coordinates. These coordinates can then give an idea which nodes are closer.

The other option is RPC "get-coordinate"!
